COMBINED DUST-PROOF BOX AND CASE FOR WATCHES.

SPECIFICATION forming part of Letters Patent No. 308,840, dated December 2, 1884.

Application filed June 13, 1883. (Model.)

To aZZ whom it may concern:

Be it known that I, CHARLES K. GILns, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Combined Dust Proof Box and Case for \Vatches, which is fully described in the fol lowing specification, reference being had to the accompanying drawings, in which Figure 1 represents a plan view of the case formed by the combination of the box and independent center; Fig. 2, a side elevation of the case-center; Fig. 3, a side elevation of the dust-proof box; Fig. 4, a vertical section of 1 the same,taken on the line a; 00, Fig. 3; Fig. 5, a vertical section showing the box and the case-center arranged and combined to form a complete case, the section being taken on the line y y Fig. l; and Fig. (3 a plan view of the winding-stem adapted for use with this case.

I have heretofore filed (May 31, 1883,) an application for patent for an improved dustproof box for watches.

My present invention is an improvement upon the invention described and shown in my prior application, the object of the present improvement being to construct the two parts of the box so that they may be combined with an independent centerto form a complete case,

which enables me to provide both"box and case in a simple and cheap way.

I will proceed to describe the construction and operation of my invention as I haveembodied it one form, and will then point out definitely in the claim the special improvements which I believe to be new and wish to secure by Letters Patent.

. In the drawings, A represents a dust-proof box constructed and adapted to receive a watch- 40 movement of any ordinary description. The front, a, of this box holds the crystal, as in my former application, to which reference has been made, and the box a is simply of such form as to receive the movement. The one 4 5 part is secured to the other by screw-threads, as shown in the drawings, or in any other suitable way. This box, however, instead of having a plain side, as in my former application, is provided with flanges or edges a projecting out beyond the central portion of the box, as shown in Fig. 4 of the drawings, in which one of these extended edges or flanges is placed on each box. These flanges are ar ranged a little distance apart, so as to leave an annular groove all around the box when the two parts are put together. A case-center, 13, is made of ordinary form, but is indcpendent of the other parts. The annular groove about the box is adapted to just re ceive this center, so that by separating the two parts of the box, placing the center on the body of the box, and fastening the two parts of the latter together again, a complete case will be formed, as shown in Figs. 1 and 5 of the drawings.

Vhen used simply as a box for exhibition or transportation the two parts a a only are necessary 5 and it is obvious that in this form I have a perfect dust-proof box,within which the movement may be placed, the appliances for making it entirely dust-proof described in my prior application being applicable to this construction also.

\Vhenever it is desired to mount the watch in a case it is only necessary to take the box apart, apply the casecenter, as described above, and the watch is complete for use. It will thus be seen that with three pieces I make either a box or a case, and hence it must be evident that the production of a dust-proof box and the case, within which thelattermay be mounted, is very much cheaper.

, This improvement may be used with or without a stem-wind attachment.

In the drawings I have shown the box adapted to theapplication of a stem-wind, an aperture, a, being made in the side for the insertion of the windingstem C, which is mounted in the pendant Z) of the center. In this improvement I make the box-aperture a flaring or cone-shaped, and thread it, and also make a beveled or cone shaped section, 0, 011 the stem between the collar 0 on the outside of the box, and the inclined collar 0 on the inside of the box, which is intended to adjust the setting mechanism described in my prior application. This bevel-section c is adapted to fit the aperture a in the box, and is also threaded, so as to be turned into the latter. The threads of these parts are arranged opposite to the turn of the windthat is, with the working movement of the screw opposite to the windso that in winding the watch the stem will first be unscrewed from its seat, and

ICU

then thefurtherturning of the stelnin the same direction will complete the windin After this is accomplished the stem is turned back, by which movement it is again screwed into its seat, and the collar 0 drawn tightly down into and around the opening in the box, there by making a perfectly dust-proof joint.

I do not limit myself to the precise form and construction of the several parts, as described above and shown in the drawings, for they may be modified in details, and yet the main idea of my invention retained by con structing the three parts at first described, so that they may together form a watch-case, or two of them be used to form a dust-proof box for the reception of the watch movement.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A dust-proof box for watch-movements, the frontand back of which are constructed and adapted to form corresponding; parts of the case and to clamp and hold the center in place, in combination with a ring-center made in a separate and single piece adapted to be applied to the box, whereby the center may be applied to the box and secured between the front and back by clamping without further fastening, thereby transforming the box into a complete case, all the parts of which are fixed and stationary, substantially as described.

2. A dust-proof box for Watch-movements, provided with projecting flanges or edges arranged one on the front and one on the back section of the box, in combination with an independent ring-center separate from the other parts of the case, and adapted to be fitted and clamped between the said flanges of the box, whereby all the parts are secured together in a fixed and stationary position without further fastening to forni a case, substantially as described.

3. The dust-proof box A, composed of the two sections a a, each provided with a projecting edge or flange, a, in combination with the case-ring center B, adapted to be applied to the box between the flanges thereof, thereby transforming the box into a case by the combination of these three parts only, substantially as and for the purposes set forth.

4-. In a stem-winding watch,a windingstem provided with a threaded section and a collar outside of said section, in combination with a movement-box provided with a threadedstein aperture, the threads in each case being constructed to work in a direction opposite to the winding-turn, substantially as and for the purposes set forth.
